rlhis invention relates to furnace arch contion.

A5 various other forms, all within :'55 manner of ennaloying @ther objects will be pointed ont or indi-L cated hereina ter or will be apparent upon an understanding of the invention or its einployment in practice.

o ln the drawing formino; part oi this spec-- view of a hariay i view siow- Eig. #l is a top vie v trated in Fig. 1.

"f J' r i! .in various forms or s speneed arches ioL 'furnaces and the like, the refractories which M constitutethe arch are suspended by supporting` members from a ranieri'ori; or from metallic beams which are disposed above the arch and which it is desirable be spaced above the arch in order that they may be afforded the requisite cooling to prevent their becoming overheated and losing their stiiness and tensile strength. The refractories in the arch are subject to wearby erosion and other influences attendant upon furnace operation7 and it vis desirable that the structure removed veryreadily, and without involvinci4` adord facilities whereby th i retractories may be re Jlaced from time to time. Aln order that such replacements may be made in comparatively limited areas of the furnace arch, it is desirable that the various cornponen:J sections or porgions of the arch l' inde endentl 1 supnorted so that such as q l i need repair Aiay be removed and replaced without involving' an extensive demolition or the structure. The present invention provides hanger which may be applied and displacement off portions of the structurev which it is not desired to remove, and '1 facilitates the making; of repairs in a limited portion of the arch structure.

The nafire' ot the invention may be ascertained rea y 'from the example illustrated in the drawing. rlhe hanger includes a beamengaging1)` member having` oppositely disposed arm. portions -10 and 11 which are connected by a. yoke por tion 12 that is provided with an aperture LP. At their other ends the arm portions'are provided with averhanging lugs or shoulders 14 and 15 extending toward each other and spaced apart by a distance less than the width oit the beam iianges for which the ani-engaging member is adapted. Thearm is bowed outwardly to an extent somewhat eter than the arm 10, so that its overhangingv lug portion is somewhat longer than the opposite lugportion 14. @n the arm 11 below the lug' 1,5 is a stop shoulder 16, the end iace of which is of approximately the samespacingI from the axis of heaperture 121 as is the inner face of the arm 10 adjacent the lug 14. The. end tace of the stop lug 16 and the inner face ot the arm 10 adjacent the lug;` 14 are spaced apart a distance only slightly exceedingthe width of the l-bearn iianges for which Vthe hanger is designed. The vspace below the stop lug 16 is adapted to accommodate one oit the beam flanges when the beamengagjing member is applied to the beam ina a laterally tilted position, as illustrated in Fig. 2, thus permitting the lug. 14 to bedisplaced sufficiently to clear the ropposite beam flange as the beam-engaging member is brought back to the upright position.y rlllhus both ianges of the beam may be introduced into the span of the beam-engaging member, so that the lugs 14. and 15 will overlie the opposite anges, and when said lugs are resting on the beamianges, the stop lug 16 and the inner side ot the arm 10 Will prevent the beam-engaging member shitting laterally to a point waere either oi the esvvill be disengaged .uw i .v i V' i' e `i ile i ine learn ages. ln tins position, trie which rests that the etlie rod 17 to per limited extent or swinging movement. The

engagement otl the beam-retaining member "L" i f. on beam liar.

ges is snch that it may be shifted longitudinally thereon, and that it may permit also of sv ging or tilting movement longitudinally ot the beam. rlhus the hanger al'ords flexible or pendulous support for the arch portion which it carries.

'i A hanger of this construction is or" particular ad .ntage in that it may be placed at any point on or removed from a beam Which is already permanently installed, Without involT-.fing displacement or adjustment ot associated hangers. Because ot the integral construction ot the beam-engaging member, furthermore, it is particularly qualified for heavy service and Jfor use Where clamping members and the like, involving adjustable features, are likely to be rendered inoperative oy rust or dirt. A eem-engaging member of -he sort herein described may be formed ishingg` operations in order to quality it for successful operation, and hence may be made quite economically in sizes and proportions requisite to support quit-e heavy loads. lNher the beam-engaging members must necessarily be of considerable size for sup-V a beam-engaging member having oppositely arranged arms spaced apart and terminating in overhangmg lug portions extending to- Ward each other and spaced apart by a distance less than the Width of the beam ianges 'for which themember is designed, one 'of said arms having stop lug below the overhanging lug for cooperation With the opposite arm to prevent the overhanging lugs shifting out t the hangerV it the latter a of engagement with the beam flanges, the arm affording space beloiv said stop lug permitting the insertion of one of the beam i'langes to a distance permitting the overlianging lug of the opposite arm to clear the opiosite beam flange.
